Simple but useful remix to add a keyhole peg to a flat T-Bolt to mount anything from power strips to small routers or switches. Also thread is shortened to make it compatible with surface-mounted multiboards.
The keyhole dimensions are 6.8mm for the top diameter and 3.5mm the center shaft with about 2mm depth.
The author remixed this model.
Added a simple keyhole peg to the top of the bolt and shortened the thread to make it flush on the back for compatibility with surface-mounted multiboard.
